Coordinate the disrupted supply chain based on self-organized criticality and extreme value theory 基于极值理论和自组织临界特性的供应链突发事件协调
The paper also discriminates the relationship between the negative power and scales, it is found that the character of self-organized criticality of China disaster exposure exists objectivity, but the value of the negative power of relationship between the scale and frequency may change with different scales. 最后指出,中国自然灾害灾情的自组织临界性特征是客观存在的,而标度-频度的幂律值则是一个相对值。
These exact analytical results not only provide basic physical understanding of self organizing criticality and phase transition behavior in traffic flow complex systems, but also present directive value for the information management and real traffic controlling of high way transportation systems. 这些精确解析结果的获得既对于交通流复杂系统的自组织临界性和相变行为提供了基本的物理理解,又对于高速公路实际交通运输的信息管理和控制具有指导意义。
The special characters of spare parts inventory management based on continuous production and its four control characteristics, i.e. criticality, specificity, demand pattern and value, are discussed. 分析了连续生产模式下备件管理的特殊性,讨论了相关性最强的四个备件控制特征备件重要性、通用性、需求模式和价格。
